An apparatus to realize personalized cosmetic compositions including a formula supply assembly having a plurality of additive reservoirs that contains a plurality of additive substances, a plurality of additive pumps that supplies selected additive quantities of the plurality of additive substances, a base reservoir that contains a base substance, and a base pump that supplies a base quantity of the base substance and a mixing assembly having an additive inlet that receives the selected additive quantities, a base inlet that receives the base quantity, and a mixing channel that mixes the additive quantities with the base quantity to form the personalized cosmetic compositions.

The invention provides a method for validating the functioning of an apparatus with a static mixing device for mixing two liquid streams for producing nanoparticles. The static mixing device may be a jet impingement reactor. The method is based on the use of PLA, PLG or PLGA for producing polymeric nanoparticles with highly reproducible particle sizes. The invention further provides kits and liquid compositions for carrying out the method.

An apparatus for mixing a liquid and a substance, including a housing with a liquid inlet and a substance inlet to a mixing chamber, an outlet for a mixture of liquid and substance, and a flow restrictor arranged in the housing, between the liquid inlet and the mixing chamber. The flow restrictor is controllable to switch between a first position providing a first through flow area configured to create a Venturi effect such that a flow of the liquid draws the substance into the mixing chamber, and a second position providing a second through flow area that is larger than the first through flow area to thereby decrease a pressure drop caused by the flow restrictor.

A split casing fluid device includes a reaction chamber including a first and second casings having a portions of a stator, a rotor rotatably mounted inside the stator and having a plurality of fluid-interacting features, the rotor exterior surface and the stator define a fluid passageway therebetween, an inlet into the reaction chamber in fluid communication with the fluid passageway, and an outlet from the reaction chamber in fluid communication with the fluid passageway. Removal of a casing creates an opening in the reaction chamber sized to allow passing the rotor through the opening. In some embodiments, the casings span the entire length of the rotor and removal of at least one casing creates an opening in the reaction chamber sized to allow removal of the rotor in a perpendicular direction to the longitudinal axis. The fluid device may be a cavitation generator with a rotor having cavitation-inducing features.

A tintometric machine includes an external frame made from rigid material, which defines an internal area. The internal area houses at least one dispenser system, which can dispense at least one fluid, such as paint or dye, into a vessel or container. The dispenser system of the tintometric machine, includes one or more dispenser mechanisms and a plurality of canisters or containers. Each of the dispenser mechanisms includes at least one pump and at least one valve assembly, and the canisters or containers are connected to one or more dispenser mechanisms. The external frame of the machine has a shell-shaped structure that can be opened to divide the machine into at least two portions. Each portion contains a part of the dispenser system. By dividing the machine into portions, an inspection area is defined between the portions, which is accessible to an operator.

Disclosed is a stirring device (D) including a screw shaft (1) driven by a drive unit, the screw shaft (1) being guided with respect to a body by way of a bearing, the stirring device furthermore including a seal (8) rigidly secured to the body and in contact with the ball joint (7) so as to ensure sealing with respect to the fluid to be stirred. The seal (8) is mounted on a seal holder (9), the seal holder (9) including a contact region (10) and being able to take up two positions, a first, operating position in which the seal (8) is in contact with the ball joint (7), and a second, maintenance position in which the contact region (10) is in contact with the ball joint (7).
